Fused Layer Deposition of Lunar Regolith

In order to enable lunar exploration in a sustainable manner, it is necessary to develop technologies that allow the use of lunar resources in-situ. Additive manufacturing techniques are being studied for in-situ resources utilization on the Moon (e.g.: solar or laser sintering). The results of these studies, presented samples with low mechanical properties due to the formation of defects and cracks within the final product.

Additive Manufacturing of pure copper electromagnetic coils
In space, copper coils are used for attitude control of satellites which are called magnetic torquer if a core material is used. The winding of the copper coils of magnetic torquer is a time consuming process, which is difficult to automate, especially because each coil is optimized for a given mission. Consequently, additive manufacturing has high potential to minimize the production time in the future, as well as to optimize winding shapes.

De-risk assessment: Additive manufacturing of soft magnetic material for satellite actuators - AMMMSA

The goals to improve mechanical and magnetic material properties for soft magnetic Ni50Fe50 specimens processed by LPBF was achieved. Tensile strength is with ~500 MPa higher than the targeted 365 MPa and close to values of conventionally processed material. Whereas, magnetic properties measured are still lower than those specified in the datasheet of PERMENORM 5000V5 material by VAC. Since the density achieved is already close to 100% it can be concluded that not only density has a strong influence on the magnetic properties.

Moon Fibres

Institut für Textiltechnik der RWTH Aachen University (ITA) and Institute for Structural Mechanics and Lightweight Design RWTH Aachen University (SLA) have already spun MoonFibres from regolith simulant. Gradel SARL uses the xFKin3D technological process to produces ultra-lightweight structural components made of various types of fibres and resin. This technology requires less material to create parts with equal structural strength as the ones produced in traditional ways. The produced parts can be 2D or 3D parts.

Bio-inspired Solutions for Space Debris Removal

The BIOINSPACED project was initiated to find bio-inspired solutions for space debris removal because the identification, orbital alignment, capture and removal of uncooperative bodies in space is incredibly complex and no fully functioning method is available to date. Biology and its evolved mechanisms often provide specialized concepts that show great transferability to technical systems.

LUPIN (Lunar Lithography Manufacturing)

Nowadays, human Moon exploration, and the consequent desire to establish a permanent settlement on its surface, represents one of the most fascinating challenge to face. The permanent presence of a human outpost very far from Earth raises the problem of the huge amount of payload required for the settlement, as well as the need of rapid and in-time supply of material and spare parts useful for all the activities carried out in-situ, including the realization of medicals tools and patient-specific back-up implants.

Design for Recycling - Mission architectures to manufacture, refurbish and recycle satellites on-orbit

The main objective of the OMAR Mission Architecture study is to identify and trade-off different mission architectures, to provide different services on-orbit. For each of the relevant scenarios, this objective shall be achieved by defining the associated system functional analysis and by trading-off different architectures and concepts of operations. Furthermore, the impact of aspects such as: operational orbit, type of serviced satellites, services provided, different levels of autonomy, and any other relevant factors is to be assessed.

Analysis of space debris recycling potential to supply raw materials for construction on the Moon

As on Earth, space debris should not only be seen as a threat. Instead, the value of waste as a recycled good should be understood. On Earth, this potential is already fully recognised. The German recycling industry alone generates more revenue than the entire European space industry. Nevertheless, this treasure was never lifted in space.

Development of a Compliant Mechanism Based on Additive Manufacturing
Compliant mechanisms (e.g. flexural joints) are applied where the relative motion of parts can be accomplished without using traditional bearings. Slender structures can be properly arranged to provide functions like accurate guiding, speed reduction, or change of motion direction. Compared to traditional mechanisms using bearings, significant improvements are expected. These include a decrease of part count number, frictionless motion transmission, which decreases losses, higher motion ranges, enhanced stiffness, and improved accuracy due to the avoidance of backlash.

De-risk assessment: Ceramic Packages for Magneto-resistive Sensors

A GSTP De-Risk Framework with RUAG Space Germany designed and demonstrated a novel, compact and robust sensor head for angular sensors for space mechanisms, using modern and advanced materials and manufacturing methods.

The final performance tests provided evidence in terms of high precision manufacturability of ceramic packages.

The robust design was found to be suitable for the harsh space environment
